I-13
The R1221 receiver combines one internal with three remote
receivers, offering superior path diversity. The radio system
simultaneously transmits on two frequencies, creating up to
four RF paths on two different 2.4GHz channels. This multi path
redundancy, plus the fact that each of the 4 receivers are located
in different locations throughout the aircraft, exposes each to
a different RF environment creating a superior RF link in all
conditions. The JR R1221 allows an optional Flight Log data
recorder (JRPA145) to be used. The flight log can be plugged
into the data port of the receiver to provide RF link data of the
previous flight, allowing the confirmation of the operational
performance of the system receiver antenna.

Important
: When using the 12X with Parkflyer receivers
(the AR6000, AR6100, AR6100e, and AR6300), it’s
imperative that these receivers only be flown in parkflyer-
type aircraft (small electric airplanes or mini and micro
helicopters). Flying receivers designed for parkflyers in
larger aircraft could cause a loss of control.
